Sound Systems

Loudspeaker Development

We support your engineering ranging from the definition of new products and sampling of loudspeaker chassis/drivers to the near-series product. For that purpose we use a comprehensive set of specialized tools, including detailed acoustic measurements for testing component samples, 3D CAD modeling of loudspeakers as well as BEM simulation of its directivity including all passive and/or digital crossovers. That way, during the development of a product already, substantial acoustic data can be acquired. Prototypes of horns, waveguides and cabinets can be built in-house virtually on the spot, so that measurements and listening tests can be  efficiently performed accompanying, complementing and supporting the designing stage of the product.

Loudspeaker Families and Line Arrays

When developing sound systems, it is mandatory to verify not only the acoustic performance of the single cabinet, but also the coupling of loudspeaker groups and the interaction within. Utilizing BEM technique, we simulate loudspeaker clusters and line arrays to test the cluster performance and array coupling with various curvings. This allows us to predict and optimize the acoustic performance of large and complex sound systems without the need for numerous expensive prototypes.
